Abstract
Wipers for sliding electrical contact have a form with gradual and progressive reduction in width and therfore decreasing stiffness and mass as they proceed towards the tip. This form results in higher resonant vibrational frequencies, enabling a wiper to follow the contact surface in high speed motion with less contact force. The lower contact force in turn produces less wiper distortion and consequently less hysteresis and wear.
